设置序列的last_value字段为指定数值并且将其is_called字段设置为true,表示下一次nextval将在返回数值之前递增该序列。 setval(regclass, bigint, boolean) bigint 重置序列对象的计数器数值。功能等同于上面的setval函数,只是is_called可以设置为true或false。如果将其设置为false,那么下一次nextval将返回该数值,随后...

我想将文本变量“123124126”传递给这个函数,并在表中搜索这个id。我尝试了很多选择,比如: act.action_id = any(string_to_array(iActionMasterIdList)) act.action_id=任何('{'||iActionMasterIdList||'}') 但什么都不管用。每个抛出不同的错误。我不是邮报专家,你能给我建议吗?
在上述查询中,"table_name"是要查询的表名,"json_column"是包含JSON对象的列名,"key"是要提取的JSON键名,"value1"和"value2"是要排除的特定值。 这个查询将返回满足条件的所有行,其中JSON对象的指定键的值不在给定的值列表中。 对于PostgreSQL的云计算解决方案,腾讯云提供了云数据库PostgreSQL,它是基于开...
